Hello all,
I am new to the Lucene scene and have a few questions regarding the term
boost physolophy:
Is the term boost equal to a term weight? Example: If I boost a term with
0.2 does this mean the term has a weight of 0.2 then?
If this is not the case, how is the term weight of the query calculated
then? Formula? Are there parts in it which I cannot influence? Does this formular
depend on the type of Query or is it independent. Maybe somebody can provide
a small code example?
Give the following code:
TermQuery termQuery1 = new TermQuery(new Term("contents", "house"));
TermQuery termQuery2 = new TermQuery(new Term("contents", "tree"));
termQuery2.setBoost( ? );
BooleanQuery finalQuery = new BooleanQuery();
finalQuery.add(termQuery1, true, false);
finalQuery.add(termQuery2, true, false);
How can I realise that the term "tree" is double as important for search
than "house"?
Many questions I know but I am sure that the experts here can answer them
easily.
Cheers,
Karl
